To all whom it may concern:

lie it known that I, Cnannns KATznN- nnnenn, a citizen of the United States, and a resident of Hoboken, county'of Hudson, and State of New Jersey, have invented a new and useful Composition of Matter for Destroying Insects, of which the following is a full, clear, and exact specification.

My invention has for its object to provide a composition of matter designed to be employed for destroying mosquitos, flies, or like insects in buildings, or other structures, and which is preferably made in the form of an inflammable candle adapted to be ig nited for impregnating the atmosphere with fumes having properties which are destructive to the insects, but are non-injurious and pleasant for a person to inhale as well as being free from any damaging action upon the texture, or colors of fabrics, draperies, clothes, or other articles.

My composition of matter consists of the following ingredients, combined in the proportions stated, viz:

(hrysanthcmum cinerariacfolium (buhach) 6 pounds. Fine particles of pine wood (sawdust) 3 pounds. Sanguis dr-iconis (dragons blood powdered) ounce. (lumini-rc. a galhanum -s 1.; ounces. Gunnnl tragacantlue 2 ounces,

through the infected parts of the buildin or structure.

But when it is preferred to employ the composition in the form of candles a sutlicient quantity of the water is incorporated in the mixed ingredients, and by any suitable method of stirring or grinding a mass will be produced of a consistency wherein its particles will adhere together. The mass may the be rolled into sheets,

and candles preferably of a triangular shape ,The candles are subsequently allowed to dry at a. moderate temperature, after which one, or more may be used by being supported upon a suitable vessel, and ignited so that the fumes therefrom will inlpregnate the atmosphere of the place in which. the insects are confined.

The talc in the composition does not support combustion but becomes a soft and sticky mass under the action of the water of crystallization of the tale, potassium nitrate, and the sticky residues derived from the other constituents of the composition when a candle formed therefrom is destroyed by slow combustion. The ash resulting from the combustion of the compo s1tion is retained by the sticky mass formed about the tale as a basis, The residue of combustion is thus prevented from scattering.

Having thus described my invention, T claim as new and desire to secure by Letters Patent The herein described composition of matter including buhach six pounds, line par ticles of wood three pounds, dragons blood powdered one-half ounce, galbanum .one and one-half ounces, gum tragacanth two ounces, potassium nitrate two ounces, means for preventing the ashes formed by burning the composition from scattering, said means comprising talc two ounces, and sullicient water to produce a pasty mass of the said ingredients as described and for the purpose specified.

This specification signed and witnessed this twenty-second day of November it. ll. 1912.
